Abstract
A first transformer includes a first quad core with four first legs and first windings wound around each of the first legs such that a winding direction for diagonal ones of the first legs is same. A second transformer includes a second quad core with four second legs and second windings wound around each of the second legs such that a winding direction for diagonal ones of the second legs is same. The first four legs and second four legs are arranged adjacent to, but spaced away from, each other to define four gaps. The first windings and second windings are in parallel.

A magnetically integrated quad-core transformer system comprising:
- a pair of quad cores each having a set of legs arranged such that the legs are spaced away from, each other to define four air gaps of two different widths;
- and
- primary and secondary windings wound around each of the legs, wherein one of the quad cores and the primary and secondary windings wound around the legs thereof define a first transformer, wherein the other of the quad cores and the primary and secondary windings wound around the legs thereof define a second transformer, wherein the primary and secondary windings of the first transformer are electrically in parallel with the primary and secondary windings of the second transformer and wherein at least some of the primary and secondary windings of the first transformer are wound around a diagonal pair of the legs of the first transformer.
A transformer system comprising:
- a first transformer including a first quad core with four first legs and first windings wound around each of the first legs, wherein at least some of the first windings are wound around a diagonal pair of the first legs;
- and
- a second transformer including a second quad core with four second legs and second windings wound around each of the second legs, wherein the first four legs and second four legs are arranged adjacent to, but spaced away from, each other to define four gaps of two different widths, and wherein the first windings and second windings are electrically in parallel.
